[Zope-dev] Zope 2.8: ZODB fix breaks undoable_transactions
Hi! http://svn.zope.org/?view=revrev=30334 changed the behavior of undoInfo() in a way that is not backwards compatible. See http://www.zope.org/Collectors/Zope/1822 for details. I can see 3 ways to resolve this: 1.) restoring the old behavior of undoInfo() in ZODB 2.) restoring the old behavior of undoable_transactions() 3.) propagating the change to all the code that depends on undoable_transactions() I don't know all the reasons why undoInfo() was changed, so I don't know if reverting the change is an option. If 1.) is no option, I would prefer solution 2.) over 3.) Any opinions?

I don't know when the implementation got out of synch with the docs, AFAICS there were no related changes in App.Undo.UndoSupport or undo.dtml within the last 5 years, so I guess the 'broken' behavior existed for quite a while and all existing code that uses undoInfo() or undoable_transactions() depends on the old behavior. but however people want to resolve this I will not leave the implementation disagreeing with the docs. Don't know what other people think. I believe restoring the old undoInfo behavior and adjusting the documentation would be the best solution.

behavior and adjusting the documentation would be the best solution.
Fixing this in undoable_transactions would fork the behavior of both
methods and fixing all products that depend on the old behavior would
cause unnecessary trouble.
Can you document the behavior you want? Because there were multiple
bugs in the implementation before, I'm not exactly sure what old
behavior was in all cases; I'm certain that _some_ of it was purely
accidental, never intended, and utterly surprising (when last 0).
ZODB/interfaces.py's IStorageUndoable.undoLog documents the current
behavior, which matches what ZODB's UML docs have always claimed
behavior should be. This behavior is tested in ZODB too now, so any
change here requires fiddling code, docs and tests. If Zope requires
particular behaviors, it should grow tests for those too.
I'd be happy enough changing `first` and `last` to act like Python
slice indices instead, with the caveat that because there's other
weird non-Python behavior mandated when last 0 (then undo{Log,Info}
are documented as taking the absolute value of `last` as being an
upper bound on the # of results to return -- and old behavior was
related to that, albeit with bugs of its own), they cannot act like
Python slice indices unless `first` and `last` are both non-negative.

Zope 2 uses 'undoInfo' only in one place: 'undoable_transactions'. And
'undoable_transactions' is only used for the undo tab.
CMF uses 'undoable_transactions' in a similar way than Zope 2. The
problem with the CMF code is that it should work in a consistent way
with Zope 2.7 and 2.8.
These are the two use cases I'm aware of. Both only use last 0 and
both expect slicing behavior for positive values, e.g. these conditions
should be True if we don't change undoable_transactions::
db.undoInfo(0, 20) == db.undoInfo(0, 99)[0:20]
db.undoInfo(20, 40) == db.undoInfo(0, 99)[20:40]
I don't care very much *how* this is resolved. All I want is to get the
regressions in Zope 2 and CMF fixed.

2.) When I save the work, I don't know where is goes or how to get it

Just seems that the documentation gets vague on these issues.
Looking for some enlightenment.
It sounds as though your browser has invoked WinWord as the helper for
the ExternalEditor stub file, which has the data you describe in it.
You want to associate the EE helper application ('zopeedit.py') with
that mimetype, 'application/x-zope-edit'.

I have a synkronisation script that I run every 10 minutes via wget from
a cron job.
Sometimes the script runs longer than 10 minutes.
In that case I would like to return a page to wget, but not run the
actual script.
So in a external method/module I have a function like this:
Excuse me, but I really believe trying to solve this situation within
Zope is getting at it from the wrong side.
It is so much easier to wrap the call to wget in a shell, python, perl,
whatever script. Then you can use a simple lockfile to see if another
wget is still running in a copy of the script. It will take you 10
minutes and you will have solved the problem (at least for the use case
of wget being run from the same machine).
As for making a lock inside Zope, I have done this with setting a
property:
if treeroot.hasProperty('currently_parsing'):
treeroot.manage_changeProperties( currently_parsing = True )
else:
treeroot.manage_addProperty('currently_parsing', True, 'boolean')
get_transaction().commit()
For me it never worked inside the SESSION object (for my use case it
does not matter that the session will do the locking only per user).
After I'm done, I do:
treeroot.manage_changeProperties( currently_parsing = False )
get_transaction().commit()
I don't know if this is the proper or cleanest way to do it, but
It Works(TM).

Sascha

Just FYI, having another webserver do authentication and making that work nicely with Zope Sucks with a Capital S. Most of the time there is no valid reason to go that route, other than the lame excuse but we only know it this way. I am sure that is why I am told to use Apache instead of LDAPUserFolder. There is very little documentation, very little, in regards to Apache authentication methods. There seems to be quite a bit of documentation in regards to LDAPUserFolder. I inherited this project of upgrading and the guy who initially set up 2.5.1 is no longer here for reference. Tim Requests for Zope should be proxied/rewritten through and Zope can do the authentication itself.

select 1 to drive the options displayed in select 2. When the user
makes a selection in select 1, onChange calls a Javascript function
that should write select 2 options based on the result of a call to a
Python script, passing the select 1 choice as an argument to the Python
script.
But: I cannot get the Javascript var into the namespace that the TALES
expression knows about.
Example:
script
function makeDropDown() {
var widget = document.getElementById('select1');
var choice = widget.options[widget.selectedIndex].value;
var data = [result of calling Python script 'foo(arg)' with
arg=choice]
// create options for select 2
}
/script
[various html...]
select id=select1 onChange=makeDropDown()
[options...]
/select
I've tried with multiple scripts, where one has tal:content=... but
cannot figure out how the TALES expression can get at what my
javascript gets from an event. I haven't done much with JavaScript
inside Page Templates, so perhaps I'm going about this all wrong.
TIA,
Rob

Re: [Zope] TAL and Javascript
What I do when the javascript gets too hairy is to stick it in a DTML
Method and then do something like this::
script type=text/javascript tal:content=structure
here/the_script_dtml/script
or
script type=text/javascript tal:content=structure
python:here.the_script_dtml(here, request, parameterX='Y')/script

You have two options: Either use the Javascripts onClick to make an XML call to the server to fetch the new data (not trivial) or send all the data from the start.

This is impossible, at least in a single request. You are trying to mix
server-side and client-side actions.
You would have to make a new request on the server with the contents of
'choice' in order to get it processed. This can be done with XML-RPC or
some other options; look up 'AJAX' to get a feel for this.
Alternately, if you have a known list of values for 'choice' you could
generate all the 'data' values for each 'choice' value, encode them in
the page's javascript, and look them up client-side.

Re: [Zope] TAL and Javascript
Rob,
As others have pointed out the approach you indicate will not work.
To summarize -
Write python script to dynamically create JAVASCRIPT code (you can
format javascript arrays of data from your db this way).
Then, using TAL load it in, eg
head
tal:js replace=structure
here/python/pythonThatCreatedJavaScriptjavascript here/tal:js
/head
Which is then callable from the other javascript routines in your page.

[Zope] TAL and Javascript
Thanks to all the responders. It gave me some ideas, but alas no luck.
To clarify, I am not trying to do everything in one request. Request
one generates the page, a user event (selecting an option from a form)
fires another request via javascript.
like:
script tal:content=python:'function getFormats() {
var widget = document.getElementById('orgs');
var chosen_org = widget.options[widget.selectedIndex].value;
var formats = %s;
// build selection 2 options from formats
' % here.getDataFormats(chosen_org) /
And then a user event (onChange) calls getFormats.
Even with generating the script with a Python script or DTML, the
problem remains (for me at least) to get a value from the DOM passed as
an argument to a Python script that queries my database. If my Python
script didn't take an argument, I'd have no problem. I could do this
and use javascript to build the select options from the appropriate
values. But I'd like to cut down on what the browser has to handle.
What the user chooses in the first selection can reduce what they get
to choose in selection two from 3000 choices to hundreds. I'd prefer to
have the backend reduce the result set rather than having the browser
do the work.
I thought about AJAX (no experience), but given time constraints, looks
like I'll have to load everything on the page and go from there.

I do not see it creating another request. I see a DOM event. DOM events
do not touch the server.
like:
script tal:content=python:'function getFormats() {
var widget = document.getElementById('orgs');
var chosen_org = widget.options[widget.selectedIndex].value;
var formats = %s;
// build selection 2 options from formats
' % here.getDataFormats(chosen_org) /
And then a user event (onChange) calls getFormats.
Even with generating the script with a Python script or DTML, the
problem remains (for me at least) to get a value from the DOM passed as
an argument to a Python script that queries my database.
Again, as I understand you, this is impossible.
Zope has no access to the DOM. Only to request parameters. This simply
cannot work. ZPT can only insert values during page rendering, and the
value for 'chosen_org' is decided after the page is rendered and in a
browser. Unless you can invent a special time-traveling Javascript, this
cannot work.
What would work is::
script tal:content=python:'function getFormats() {
var widget = document.getElementById('orgs');
var chosen_org = widget.options[widget.selectedIndex].value;
var formats = xmlrpcserver.getDataFormats(chosen_org);' /
This would actually create another request to Zope, running a script
with you're dynamically generated value. Note: I don't know how xml-rpc
is done in JavaScript, so I just made something up. Presumably
'xmlrpcserver' is a handle on your Zope server. Also note that every
time someone fires off this method, it's a request to the server.
(Also note: it doesn't have to be XML-RPC, just some way of asking the
server. There are various methods used for this.)
You might also make the widget that you chose from be part of a form,
and when a value is chosen, the form is submitted. This will get the
'chosen_org' in a request, and your template can then render your second
select list with the values from::
'here.getDataFormats(request.chosen_org)'
This is the common 'old-school' way of doing this.

I'd prefer to have the backend reduce the result set rather than having the browser do the work. We do this a lot... a few key concepts to get you going: 1) You can embed dtml tags within javascript, eg: hiddenframe.location.href = 'dtml-var baseurlSub_GetPresentorPage?confid=dtml-var login_idSessUpd=1' This allows you to write scripts which generate javascript code that is specific to the situation (when zope processes the dtml tags, the tags will be replaced with 'data' which then becomes part of the javascript code). 2) You can set javascript variables from dtml/scripts, eg: parent.presentorpage= 'dtml-var temp_folder.getProperty(confid+'_CurrSlide')' This allows you to store zope objects/fields/etc in variables that javascript can then use. 3) We use hidden html frames to provide a location that javascript can reload in order to make 'invisible' (not really, but close enough) calls from the browser to the server hth Jonathan ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
